Spring- Throttle Return 16562-Z4E-S10

This throttle return spring pulls the engine linkage back toward idle when the throttle is released. A stretched, rusted, or broken spring may leave the engine running too fast or cause an uneven idle. Check the throttle plate, cable, linkage, and nearby governor parts for dirt or binding before changing the spring. Use the full engine model, type, and serial details to confirm fit. Shut off the fuel, let the engine cool, and disconnect the spark plug lead. Hook the spring into the exact holes shown in the diagram without bending or stretching it.
